JACOB VEYERMANN, OF BARCELONA, SPAIN.

SHAKlNG-BOLT.

SPECIFICATION forming part of Letters Patent No. 584,436, dated June 15,1897.

Application tiled MMC-l1 13, 1396. Serial No. 583,105. (No model.)Patented in Spain April 10, 1894, No. 15,689; in France July 16,1894,1l0. 239,994,1tndin Switzerland October 5, 1894,110. 9,414.

To all to-hom, it lita-y concern-r Be it known that I, JACOB W EYERMANN,a citizen of the Republic of Switzerland, and a resident of Barcelona,in the Kingdom' of Spain, actually at Zrich, in the Republic ofSwitzerland, have invented certain new and useful Improvements inSitting-Machines, (for which I have obtained patents in France, No.239,994, dated July 16, 1894; iu Spain, No. 15,689, dated April 10,1894, and in Switzerland, No. 9,414, dated October 5, 1894,) of whichthe following is a specification.

My invention has relation to flour-bolts, and more particularly to boltsin which the material is kept in motion or alive by imparting to thebolt a circular or gyrating motion in a horizontal plane.

The invention consists in means for suspending the bolt from itssupports, whereby a uniform and regular gyrating motion can be impartedto such bolt and the detrimental irregular vibrating, shaking, orjarring movements due to centrifugal action and inherent to this classof machines are reduced to a minimum, it' not altogether avoided.

The invention further consists in the means for forwarding or moving thematerial through the machine, in the means for preventing the meshes ofthe bolt-cloth from choking up, and in structural features, as will nowbe described in detail, reference being had to the accompanyingdrawings, in which Figure l is a vertical transverse section through thebolt-casing, taken on the irregular line :t of Fig. 2, which latter is afragmentary plan view of the bolt-casing. Fig. 3 is a longitudinalvertical section through one of the compartments or divisions of thebolt-casing. Fig. l is a horizontal section taken on the line ,az ofFig. 8. Figst and 6 are transverse sections ot the collecting andforwarding plates or boards.- Fig. 7 is a side elevation, and Fig. 8 anend elevation, ot a bolt such as shown in Figs. 23 and ,L. Fig. 9

is a side elevation ot a smaller bolt, and Figs. l and ll are sectionaldetail views.

Referring to Figs. 7 to ll, M indicates the bolt-casing, having on itsunder side a crossgirth fm, midway of its length, that is provided witha socket-bearing for a wrist-pin projecting from a crank-disk N, that issecured to a vertical shaft N', carrying also a belt-pulley n', wherebya circular or gyratin g motion can be imparted to said casing. The shaftN'has its bearin gs in a suitable tubular standard secured to abed-plate G, to which are also secured the standards E, from which theboltcasing M is suspended, said standards being arranged on oppositesides of said casing and are tied and braced together Vin pairs by meansof cross-braces E2 and by mea-ns of tierods F. The lower or inner endsof the tierods F are pivotally connected with a standard G', while theupper or outer screw-threaded en ds ot' said rods extend through theirrespective standards E and are tied thereto by means of nuts n2 and nl,whereby the rigidity of the supports for the bolt-casing M is insured.

Each standard E has a bracket-arm E' on a split or clamping sleeve lilo,fitted on a cylindrical portion of said standards between a circularila-nge e and a iianged cap-nut e', said sleeves being provided withlugs or ears for the clamping-bolts e2, whereby the position of thebracket-arms from which the boltcasing is suspended relatively to saidcasing may be varied within certain limits, and therethrough thecircular or gyrating motion of said casing.

Then a short bolt-casing is employed, two standards E will suffice forsupporting the same, as shown in Fig. 9, the supporting or bracket armsin this case being made slightly longer.

The arms E', Figs. 7 and S, or E3, Fig. 9, projecting toward the feedend of the machine, are extended and constructed with a console ei", towhich is secured the board b', attached to the discharge end of the feedducts or spouts d, to which the material to be bolted is supplied, theoutlet to said ducts being connected by Flexible hose B' to the feed-boxB2 at the feed end of the machine. The bracket-arms E have asocket-bearing e4 for a bearing-block it', in which is formed ahemispherical socket for a sphere or ball 7i, at the end of asuspension-spindle H', a tWopart block h, having a like socket orbearing, being arranged above the ball h and forming with the lowerblock h' a spherical bearing for said ball, the parts being thusconnected IOO by a ball-and-socket or universal joint, saidbearing-blocks 77, h6 being held in proper position by a iianged nut h3,screwed into the aforesaid socket-bearing c4.

The spindle H" screws into the bridge 7c of a strap K, into which theupper end of the hanger-rod II is screwed, so that said rods and thebolt-casing supported therefrom can be adjusted vertically withincertain limits, which is of importance in that the horizontality of thebolt-casing relatively to the driving-crank can thus be readilymaintained and a binding of the latter in its bearings in thecross-girth m avoided. At their lower ends the hanger-rods II areprovided with a hemispherical head ho, that fits a corresponding socketh2 in the under side of bracket-arms M, secured to and projecting fromthe under side of the bolt-casing M, thus also forming a universal orball-and-socket joint between said bolt-casing and its hanger-rods. Thebearings for the lower end of the hanger-rods are protected against dustor other foreign matter by means of a nut h, screwing into thebracket-bearing, and by means of a cap h5,1itting onto said bearing, theconstruction described being clearly shown in Figs. l0 and 1l.

By means of the described connections the detrimental irregularmovements of the boltcasing M, due to centrifugal action in this classof machines and hereinbefore referred to,are reduced to a minimum,if notaltogether avoided.

The arran gement of the means for forwarding the material through anddelivering the same from the machine and their arrangement relatively tothe bolt cloths or screens will of course depend upon the intendedcapacity of the machine and upon the grading or division of thematerial-t'. e., upon the number of bolting-cloths of varying linen-essof mesh over which the material is passed.

Inasmuch as my invention is applicable to separating or screeningmachines generally, the number of cloths or screens used in the machinewill depend upon the nature of the material treated and upon the extentof its subdivision or grading, and although I have illustratedmyinvention in its application to flour-bolts I do not desire to limitmyself thereto.

In Figs. l and 2 I have illustrated a flourbolt in which the casing M isdivided longitudinally into two separate or independentbolting-compartments 1 and 2, each containing four bolt cloths orscreens, while in Figs. 3 and 4 I have shown the bolt-easing dividedlongitudinally into four separate or independent bolts l, 2, 3, and at,each provided with four superposed bolt cloths or screens, (indicated inFigs. l and 3 by the symbols a a a2 a3, respectively.) It will of coursebe understood that the bolting cloths or screens are of differentdegrees of fineness-that the upper cloth a has the coarsest or most openmesh and the cloth d3 the finest. It will also be understood that in oneor more or all of said cloths or screens the degree of iineness of themesh'inay vary from the feed to the delivery end of the cloth or screen,as is commonly the case, the variations in the mesh of a single cloth orin the mesh of the different cloths depending upon the degree ofsubdivision of the material.

In the case under consideration, if it be assumed that the meshthroughout each bolting-cloth is uniform and that said mesh increases iniineness in the successive cloths from the upper to the low-er fourdeliveryspouts would be required for each boltingcompartment in themachine shown in Figs. l to 4. It may, however, be desirable, especiallyin bolting-machines, to obtain the coarse an d fine m iddlingsseparately, in which case the upper cloth ct may for the greater part ofits length have a mesh too fine to admit of the passage of the coarsermiddlings, while for a portion of its length at the tail end the meshmay be sufficiently open to admit of the passage of such coarsemiddlings, but of course not sufficiently open to let the bran passthrough. In this case a fth delivery-spout is necessary, and such anarrangement is shown in Figs. 3 and 4, although I have deemed itunnecessary to show the varying mesh in the said upper cloth.

The feed-spout d receives the eoarser iiour that passes through thecloths a, ct, and a2, the spout d the nerour that passes through theaforesaid cloths, cl2 the fine middlings passing over cloth a', d3 thecoarser middlings passing through the tail end of screen a, and d* thetailings from said screen a, while the finest flour or dust passingthrough screen as collects on the collecting-floor S, from which it isdischarged through a suitable spout. (Not shown.)

The means for forwarding the material through the machine are moreclearly shown in Figs. l, 2, 4, 5, and 6. Above the upper cloth a, belowthe lower cloth a3, and between the cloths a a and a2 a3 are arrangedwhat I may term collecting and forwarding"7 or propelling plates orboards A, A', A2, A3, and S,respectively. They are, with the exceptionhereinafter referred to, similar in construction, in that they areprovided with hollow pyramidal projections P, preferably three-sided,projecting from their upper faces and integral with or secured to theplates or boards whichare preferably made of sheet metal and securedrigidly to the bolt-casing M. Two of the sides p2 and p3 of thepyramidal projections P are comparatively ilatthat is to say, they risegradually from the plate, while the third and wider side p is substantiallyperpendicular to said plate. rl`hese projections I are arranged atsuitable distances apart along one side or edge of the plate, so thatthe substantially vertical side p will lie at an angle to thelongitudinal plane of such plate in the direction in which the materialis to be moved and so as to leave a sufficient space between the angle aand the opposite edge y of the plate.

It is obvious that if provision is made to impart to the cloth or screenbelowa plate constructed as described a motion by which said material isthrown up against the inner face of the substantially vertical side p ofthe hollow pyramids and at the same time a movement whereby the materialis moved alternately from one side of the plate to the other, as is thecase when the screen receives a gyrating motion, the material will becaused to move in a zigzag path from one end to the other of a cloth orscreen below such plate. It is obvious that if the upward movement ofthe material is so timed relatively7 to the gyrating movements of theplate and screen as to take place when said material is caused to movetoward the edge y of the plate the oblique face of the pyramid willdirect the movement in an oblique or forward direction, so that at eachgyration ot the plate and cloth or screen the material on the latter isthrown forward a distance s ubstantially equal to that between theapices of the acute angles formed by the sides p and p2 of two pyramids,thereby effecting not only a very rapid movement of the material fromone end of the cloth or screen to the other, but said.

material is constantly kept scattered or alive during its passage oversuch cloth or screen, thereby materially expediting the bolting orscreening and at the same time avoiding the choking up or clogging oft-he meshes of the cloth or screen. There is, however, another veryimportant advantage derived from the described construction ofcollecting and forwarding plates, in that the same plate also serves tomove the material that passes through a cloth or screen above such plateto a cloth or screen below the same, the material on the plate moving,of course, in an opposite direction to the motion of the material onvthecloth or screen above and below such plate, a i indicated by arrows inFig. 3.

Although the material, under the gyrating or centrifugal action of themachine, is not only thrown or caused to move alternately from one sideto the other on the cloths or screens and on the collecting-plates, butalso upwardly to some extent, whereby such material is moved along saidplates and the cloths or screens as described, yet this movement wouldbe a comparatively slow one unless the screens and plates were arrangedin close proximity to each other, or unless a violent gyrating movementwere imparted to the bolt, which is not desirable. This can be avoidedby reversing the position of the pyramidal projections P, so as toproject from the under side of the plates to or close to the material,as will be readily understood, in which case said projections need notbe hollow. I prefer, however, toimpart to t-he material on the clothssuccessive upward movements, so timed relatively to the movements of thematerial from side to side of said cloths as to take place when saidmaterial is moving along the side p of the projections P toward thespace :c i whereby the material so thrown up is brought into contactwith the inner face of the side p of said projections P and caused to bemore rapidly forwarded in the direction of the length of the cloth orscreen, thereby also keeping the material more thoroughly scattered oralive on such cloth or screen for the purpose of expediting theoperation of bolting or screening. This upward movement of the materialhas heretofore been generally produced byimparting to the cloth orscreen a vibratory movement independent of its gyrating or to-and-romovement by means of abutments in the path of such cloth or screen or bymeans of knockers. These means are, however, undesirable, chieflybecause insufficient to pre vent the choking up of the meshes of thecloth or screen, requiring additional means, as brushes, for thepurpose, which are also undesirable on account of the rapid wear of thecloths or screens. This I eiiectually avoid and at the same time amenabled to keep the meshes of the cloths or screens free or unobstructedby securing the cloths or screens rigidly along one side only and bysecuring the other side to a pendulous bar b, weighted by a bar c, saidpendulous bar being hinged to a longitudinal girth h', Fig. l. It willreadily be seen that during the gyrating motion of the bolt the bar l)will swing alternately from one side toward the other ot' the bolt-caseM, thereby alternately slackening and stretching the cloth or screen a,the material being more or less violently thrown up and the cloth orscreen more or less Violently shaken during the stretching movement-thatis to say, during the movement of the weighted bar Z9 c from the fixedside of the cloth or screen, thereby shaking out such material as isheld fast in the meshes.

In order to avoid the location of all of the discharge-spouts at one endof the machine, it becomes necessary to provide means whereby thematerial passing through one cloth or screen a and collecting upon oneof the gathering and forwarding plates A and the material on the clothor screen immediately below such plate `be moved in the same direction.To effect this, I arrange above aplate A an additional plate A0, whichmay have solid pyramidal projections P', if desired, as shown in Fig. 6,and alsoin Fig. 3, where two such plates A0 A3 are arranged between thecloths or screens a? and a3. Of course the position of the hollowprojections P on the plate A3 will be reversed relatively to thepositions of the projections P on plate A0, in order to cause thematerial on said plate A0 and on the cloth or screen A3 below to move inthe same direction, as shown in Fig. 6 and in dotted lines in Figs. 2and 4.

The same arrangement will be necessary when a cloth or screen has avariable mesh land when a portion of the material passing IOO IIO

through a section of such cloth or screen is to be separatelydischarged, as shown on the right-hand end of Figs. 3 and 4, where thespace between the screen a' and the plate A is partitioned off by across-partition. p2 and an additional plate A is arranged above theplate A at its right-hand end, so that the material passing through thecloth or screen to the right of said partition p2 will be directed bythe projections P on plate A0 into delivery-spout d3, while the materialpassing through the cloth d to the left of the partition will .bedirected to the left end of the machine and delivered from plate A tothe screen d below it and caused to move toward the right on said screento the dischargespout d2.

By means of the construction and arrangement of collecting andforwarding plates and cloths or screens much greater quantities ofmaterial can be eifectually treated within a given time than is the casewith any bolting,

' screening, or separating machine now in use,

so far as known to me, While there is comparatively little wear ofpart-s owing to the absence of detrimental irregular movements of thebolt itself, due to centrifugal action, to the absence of the usualknockers or other appliances for imparting to the screen that peculiarshaking or vibrating motion, and to the absence of clearing-brushes.
